[349] At Sāvatthī. … Now on that occasion a great sacrifice (mahāyañña) had been set up for King Pasenadi of Kosala. Five hundred bulls, five hundred bullocks, five hundred heifers, five hundred goats, and five hundred rams had been led to the post for the sacrifice. And those of his who were called 'slaves' or 'servants' or 'workers'—they too, threatened with the rod, threatened with fear, with tearful faces, weeping, were making the preparations.
